Hi guys, 
I wonder if any of you could come up with an idea for this. I have plans that have many columns of different sizes and the size is just a  reference (C1, C2, C3 ...). I want to have the columns with reference as a block, but I need to have the option of moving the text (attribute) + it has to be constant value so that it cannot be changed by mistake (someone could change the ref without changing the actual column size). Now the tricky part is as soon as I set the value to constant, I cannot move the text.Any help much appreciated.Thank you
